Electronic device

Abstract

A novel electronic device including a flexible display is presented. The electronic device has a flexible display including an organic light emission diodes and a plurality of columnar bodies linked together. Users can transform the shape of the electronic device into a tablet, an eBook, or a hand-held gaming device. The electronic device is configured to resize its main display area in accordance with the selected mode.

What is claimed is: 
     
       1. A flexible base material comprising:
 a flexible resin plate-shaped part and an anti-deformation structure formed on a surface of the plate-shaped part, wherein the anti-deformation structure includes protrusions and depressions on the surface of the plate-shaped part, and the protrusions and depressions are shaped such that adjacent protrusions come into contact with each other when the plate-shaped part is bent and restrict further deformation, 
 wherein the protrusions includes a first protrusion and a second protrusion whose width is larger than a width of the first protrusion. 
 
     
     
       2. The flexible base material according to  claim 1 , wherein the protrusions have a three-dimensional shape having a trapezoid or rectangular cross section. 
     
     
       3. A flexible image-displaying device comprising:
 an image-displaying plate having a device layer formed on a surface of a flexible layer; and 
 a flexible base material attached to the image-displaying plate that deforms together with the image-displaying plate, 
 wherein the flexible base material further comprises a flexible resin plate-shaped part and an anti-deformation structure formed on a surface of the plate-shaped part, 
 wherein the anti-deformation structure includes protrusions and depressions formed on the surface of the plate-shaped part, 
 wherein the protrusions and depressions are shaped such that adjacent protrusions come into contact with each other when the plate-shaped part is bent and restrict further deformation, and 
 wherein the protrusions includes a first protrusion and a second protrusion whose width is larger than a width of the first protrusion, and the second protrusion keeps a part of the image-displaying plate flat when the flexible base material deforms together with the image-displaying plate. 
 
     
     
       4. The flexible image-displaying device according to  claim 3 , wherein the protrusions have a three-dimensional shape having a trapezoid or rectangular cross section. 
     
     
       5. The flexible image-displaying device according to  claim 3 , wherein the device layer includes a touch sensor. 
     
     
       6. The flexible image-displaying device according to  claim 3 , wherein the device layer includes an organic light emission diode and a circuit for controlling the organic light emission diode.
